Magnetic micro-structural uniformity of die-upset Nd-Fe-B magnets
Magnetic micro-structural uniformity of die-upset Nd-Fe-B magnets" (2012). Si-Hwang Liou Publications. Paper 101. magnets have been prepared with height reduction (h) in the range of 60 to 88%. The energy product as high as 50.4 MGOe was obtained in the sample with h $ 70%. The magnetic domains of the samples are revealed by using magnetic force microscopy (MFM). The average domain widths of th...
متن کاملMagnetic Properties Improvement of Die-upset Nd-Fe-B Magnets by Dy-Cu Press Injection and Subsequent Heat Treatment
Ultrafine-grained die-upset Nd-Fe-B magnets are of importance because they provide a wide researching space to redesign the textured structures. Here is presented a route to obtain a new die-upset magnet with substantially improved magnetic properties. After experiencing the optimized heat treatment, both the coercivity and remanent magnetization of the Dy-Cu press injected magnets increased su...
متن کاملEffect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets
Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...
